What is Quercetin Dihydrate?
Quercetin Dihydrate is a potent flavonoid, a plant-derived bioactive compound renowned for its antioxidant properties. It is one of the most abundant flavonoids in the human diet and is the form commonly used in scientific research and commercial supplements due to its favorable stability profile. The "dihydrate" designation indicates that the compound is crystallized with two water molecules (C₁₅H₁₀O₇·2H₂O), which can influence its solubility, bulk density, and handling characteristics in industrial manufacturing processes.
As a leading bulk Quercetin Dihydrate manufacturer, we understand these critical physicochemical properties. Our production process is finely tuned to deliver a consistent, fine powder that ensures optimal performance and ease of integration into a wide range of solid-dosage and functional food formulations, providing a reliable base for your product development.
Sources of Quercetin
While Quercetin is naturally present in foods like apples, onions, and capers, commercial-scale production for bulk Quercetin Dihydrate powder requires standardized and efficient sources. Our product is sourced from Styphnolobium japonicum (native to China, commonly called Chinese Scholar Tree), a well-recognized source for high 芦丁 (rutin) content, ensuring a high-concentration, sustainable, and traceable supply for industrial applications.
The Efficacy and Mechanism of Quercetin Dihydrate
The primary value of Quercetin Dihydrate lies in its powerful, broad-spectrum antioxidant activity. It functions primarily by neutralizing free radicals and chelating metal ions, which are key drivers of oxidative stress and cellular damage. This fundamental mechanism supports a range of health applications, making it a sought-after ingredient for nutraceutical and pharmaceutical formulations:
- Cellular Health & Anti-Aging: By protecting cells from oxidative stress, Quercetin Dihydrate helps support cellular integrity and vitality, which is a cornerstone of anti-aging health strategies.
- Immune & Inflammatory Response Support: It modulates the body's immune and inflammatory pathways, including the regulation of mast cells and the release of histamine, promoting a healthy and balanced immune response.
- Cardiovascular & Metabolic Health: Quercetin Dihydrate promotes healthy blood vessel function by supporting endothelial health and aids metabolic health through its interaction with various enzymatic pathways involved in metabolism.
- Exercise Performance & Recovery: Research indicates it may help reduce exercise-induced oxidative stress, supporting muscle recovery and endurance, which is valuable for sports nutrition products.
How is Quercetin Dihydrate Produced?
Our production process underscores our commitment to quality. As a reliable bulk Quercetin Dihydrate manufacturer, we employ advanced extraction and purification technologies under strict GMP standards. The process involves precise extraction from plant sources, followed by crystallization and careful drying to achieve the dihydrate form, resulting in a product that meets rigorous pharmaceutical-grade Quercetin specifications.
